Genes affected
GXYLT2 (HGNC:33383): (glucoside xylosyltransferase 2) The protein encoded by this gene is a xylosyltransferase that elongates O-linked glucose bound to epidermal growth factor (EGF) repeats. The encoded protein catalyzes the addition of xylose to the O-glucose-modified residues of EGF repeats of Notch proteins. [provided by RefSeq, Sep 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 07, 2022The c.701C>G (p.S234C) alteration is located in exon 4 (coding exon 4) of the GXYLT2 gene. This alteration results from a C to G substitution at nucleotide position 701, causing the serine (S) at amino acid position 234 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
